Nursing Elites

1. A client with diabetes mellitus is experiencing diabetic ketoacidosis (DKA). What laboratory result should the nurse monitor closely?

• A. White blood cell count of 15,000.
• B. Blood glucose level of 320 mg/dL.
• C. Sodium level of 145 mEq/L.
• D. Serum creatinine level of 1.0 mg/dL.

Correct answer: B

Rationale: A blood glucose level of 320 mg/dL indicates the need for insulin to manage diabetic ketoacidosis.

2. What are the primary pathophysiological mechanisms responsible for ascites in liver failure?

• A. Decreased liver enzymes.
• B. Increased hydrostatic pressure in portal circulation.
• C. High bilirubin levels.
• D. Fluid shifts due to decreased serum proteins.

Correct answer: B

Rationale: The correct answer is B: Increased hydrostatic pressure in portal circulation. Ascites in liver failure is primarily caused by fluid shifts from the intravascular space to the interstitial space due to increased hydrostatic pressure in the portal circulation. Choice A is incorrect as ascites is not caused by decreased liver enzymes. Choice C is incorrect as high bilirubin levels are not the primary mechanism for ascites in liver failure. Choice D is incorrect as fluid shifts in ascites are due to decreased serum proteins, not increased serum proteins.

3. A client with heart failure is prescribed furosemide. The nurse notes that the client's potassium level is 3.1 mEq/L. What is the nurse's priority action?

• A. Administer a potassium supplement
• B. Encourage the client to eat potassium-rich foods
• C. Hold the next dose of furosemide
• D. Increase the client's fluid intake

Correct answer: A

Rationale: A potassium level of 3.1 mEq/L is considered low, indicating hypokalemia. Administering a potassium supplement is the nurse's priority action to prevent complications such as cardiac arrhythmias associated with low potassium levels. Encouraging the client to eat potassium-rich foods is beneficial in the long term but may not rapidly correct the low potassium level. Holding the next dose of furosemide may worsen the client's heart failure symptoms. Increasing the client's fluid intake is not the priority action in this situation; addressing the low potassium level takes precedence to prevent potential serious complications.

4. The nurse observes that a client’s wrist restraint is secured to the side rail of the bed. What action should the nurse take?

• A. Ensure that the restraint is snug against the client’s wrist.
• B. Reposition the restraint tie onto the bedframe.
• C. Double knot the restraint to ensure safety.
• D. Leave the restraint in place and notify the healthcare provider.

Correct answer: B

Rationale: The correct action for the nurse to take is to reposition the restraint tie onto the bedframe. Restraints should always be secured to the bedframe, not the side rails, to prevent injury to the client in case the bed is adjusted. Choice A is incorrect because the issue is with the attachment point, not the snugness of the restraint. Choice C is incorrect as double knotting the restraint does not address the incorrect attachment point. Choice D is incorrect as the nurse should not leave the restraint in the wrong position; instead, it should be moved to the correct location on the bedframe.

5. A client with lupus erythematosus is prescribed prednisone. What teaching should the nurse include?

• A. Take the medication with food to prevent stomach upset.
• B. Avoid crowded places to reduce the risk of infection.
• C. Take the medication in the morning to prevent insomnia.
• D. Take extra calcium supplements to prevent osteoporosis.

Correct answer: B

Rationale: The correct teaching for a client with lupus erythematosus prescribed prednisone is to avoid crowded places to reduce the risk of infection. Prednisone suppresses the immune system, making individuals more susceptible to infections. Taking the medication with food may help reduce stomach upset but is not the priority teaching. Taking prednisone in the morning may help reduce insomnia, but infection prevention is more critical. While prednisone can lead to osteoporosis, advising extra calcium supplements is not the most immediate concern when starting the medication.
